@mlamouri: Could you please provide the sample test steps of the issue which would help us to verify the issue further.

Thanks in Advance.

Please follow these steps to check the fix:
1. Open new tab
2. Paste the following URL:
https://mounirlamouri.github.io/sandbox/autoplay/unmuted-self-link.html
3. Press Enter

Expected result: video should play without any other action (autoplay)

(if the fix did not work, the video will only play if you press the play button)

Verified issue based on steps from Comment#8 on Windows 10,7, Mac and Linux with Chrome version 65.0.3325.31.
